How to fix incorrect display of some awesome icons in linux?

Question

linux

The problem is that some icons may not be displayed (for example, the kernel icon is shown as a pencil icon, for example) on one machine and displayed on another, despite the fact that the distribution is the same everywhere. Package versions are new. All rolled at the same time and the packages are the same.

Examples

Answer 1

Finally this script helped.

use strict;
use warnings;
use Font::FreeType;
my ($char) = @ARGV;
foreach my $font_def (`fc-list`) {
    my ($file, $name) = split(/: /, $font_def);
    my $face = Font::FreeType->new->face($file);
    my $glyph = $face->glyph_from_char($char);
    if ($glyph) {
        print $font_def;
    }
}
